IMPROVEMENT lN SPRING WEIGHING-SCALES.

Specification ibrming part of Letters Patent No. 210,493, dated December I), 1878 application iled August 29, 1878.

To all whom it may concern:

Be it known that I, LEWIS E. BROWN, of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Iniprovementsin Spring-Balance Scales, of which the following is a specification:

Figure l is a perspective view, and Fig. 2 a transverse vertical section.

The invention relates to a household-scale; and consists in a construction and arrangement whereby a cheap and accurate scale is obtained.

A is a pedestal or stand, and B a hollow column, upon the inside of which is a projection, I. 1) is a piston, carrying on its upper end a platform 1 scale-pan, E, and having the spring-balance L connected to its lower end. (3 is a guide for the piston, and being provided with a cap or tlange to rest on the head of the standard 13. lo the upper end of the spring is attached a disk, it, the edges of which rest on the projection I, and through which the piston plays. H is an index-plate, adjustably attached by means of a thumbscrew, G, which passes through the standard B and screws into the guide 0. Fis a rod attached to the platform E, so as to move up and down with it, and is provided with a finger, which points to the weight on the dialplate of the object bein g weighed.

hen. it is desired to weigh any article independent of the tare, the utensil containing the goods may be placed on the scale-pan, and the index-plate adjusted so that the linger will point to zero, when the commodity may he placed in the utensil and weighed, irre spective of it.

hat 1 claim as new, and desire to secure by Letters Patent, is-

The combination, in a spring-balance scale, of the standard 13, the piston D, supporting the platform, the spring L, secured to said piston and to an annular disk, K, contined between the projection I and guide 0, substan tially as and for the purpose specitied.

In testimony whereof I have hereunto set my hand.

L. E. BROWN.
